<P>
Textual representations of tree-structured data objects can now be produced
in five standard forms:
a generic functional notation (as with Eli 4.3.x),
<A NAME="IDX8"></A>
an XML description of the data object,
<A NAME="IDX9"></A>
C++ code that will re-build the data object,
<A NAME="IDX10"></A>
Java code that will re-build the data object,
<A NAME="IDX11"></A>
and code describing the graph to the daVinci graph visualization tool
(assumes daVinci 2.1, found at http://www.informatik.uni-bremen.de/daVinci/).
It is also possible for the user to specify their own notation for
describing tree-structured data objects
(see  <A HREF="idem_2.html#SEC9">Languages describing tree structure of Abstract Syntax Tree Unparsing</A>).
<P>
Default output for terminal symbols has now been provided.
The default assumes that the internal representation for the terminal symbol
is a string table index.
Token processors establish the internal representations for terminal
symbols; <CODE>mkidn</CODE> and <CODE>mkstr</CODE> result in string table indices,
whereas <CODE>mkint</CODE> does not.
If you want to unparse a tree whose terminal symbols are not represented by
string table indices, you need to override the default output
(see  <A HREF="idem_3.html#SEC11">Overriding PTG patterns of Abstract Syntax Tree Unparsing</A>).
